tech info used in electrical work

• What are the technical information used in electrical work

  • British standards
  • Statutory documents
  • Codes of practice
  • Technical data
  • manufacturers instructions
  • Specification
• British standards (BS) publications are technical specifications or practices that can be used a guidance for the:

  • Production of a product
  • carrying out a process
  • Providing a service

  Normally the use of standards is voluntary and impose legal responsibilities only when required in specifications and codes of practice
• What is Code of practice

  • A set of regulations for the design and instillation of electrical wiring in a building
  • It's a set of written rules which explains how to achieve the standards required for safety, conduct, operational integrity and ensure industry compliance with consumer confidence
• Electrical code


  A set of regulations for the design and installation of electrical wiring in buildings
• Intention of electrical code

  • To provide standards to ensure electrical wiring systems that are safe for people and property where hazardous and/or unusual operating conditions for design and installation
• Factors considered in electrical code

  • Electric cables
  • Switchgear
  • Control equipment
• Electrical code considerations


  • Circuit operating voltage
  • Electric current capability
  • Environmental conditions
  • Ambient temperature range
  • Moisture levels
  • Exposure to sunlight
  • Chemicals
  • Explosive environments
• Wiring safety codes or regulations

  Ensure both wiring and associated devices are designed, selected and installed so that they are safe for use
• A technical data sheet is a document that summarizes the performance and other technical characteristics of:

  • A product
  • Machine
  • Component
  • Material
  • A subsystem
  • A power supply
  • Software

  In sufficient detail to be used by any skilled person, technician or engineer to integrate a component into a system or to solve issues within a system or to enable correct instillation and maintenance of a system
• Manufacturer instructions

  • Contain specific details about the product that are not readily available anywhere else
  • Must cover intended use, ways the product should not be used
  • The manner of installation
  • Correct use to ensure health and safety
  • Safe maintenance, including cleaning
• User instructions


  Should be comprehensive, easy to understand, and in the user's own language
• Following manufacturer's instructions


  Will allow one to comply with safety legislations
• Where an accident occurs and the defendant didn't use manufacturer's guidance and instructions

  It can be used against the defendant
• What are Specifications

  Document describing the materials and workmanship required for a development
• Specifications can be incredibly wide-ranging - covering the establishment of:

  • The site
  • The type of contract to be used
  • The performance criteria of the asset
  • The quality of the systems and products
  • Which standards are applicable
  • How they should be executed, and even the products to be used
• Specifications are used in

  • Construction
  • Aerospace
  • Oil
  • Gas
  • Automotive and Manufacturing
• What does Specifications not include

  • Cost
  • Quantity or drawn information
  • And so need to be read alongside other information such as quantities, schedules and drawings
• What is Statutory documents


  • Its the general term that embraces main laws passed by government, and includes Acts of Parliament, Act of pre-UK Parliaments, and Acts of the Scottish Parliament etc.
  • They are used to create new laws or to introduce changes to existing ones.
